Keywords Ball mills grinding circuit process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical mechanical and chemical characteristics. Typical examples are the various ores minerals limestone etc.

Ball mills can be used to further break down or refine a single material or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle but on a much larger scale.

Xinhai multiple types of wet overflow ball mills and cone overflow ball mills with some huge share of domestic and foreign ball mills market. The reason why Xinhai overflow balls can be applied such widely in grinding process is that Xinhai is committed to innovate and develop constantly optimizing the overflow ball mills.

Importance of Ball mill. Ball mill is generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mill Ball mill must be operated in a closed system with oversize ball mill material continuously being recalculated back into the ball mill to be reduced.

3.7/5(11)The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency and ultimately affects the output of the ball mill.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50 of the mill volume and its size depends on the feed and mill size.

OverviewThe high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs which has in turn made many low-grade high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al. 2012).
